Given numbers are 290,551,899,860,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 290,551,899,860,138 is 1013586540.
Find LCM of 290,551,899,860,138 with Prime Factorization
| 2 | 290, 551, 899, 860, 138 |
| 5 | 145, 551, 899, 430, 69 |
| 29 | 29, 551, 899, 86, 69 |
| 1, 19, 31, 86, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 29 x 1 x 19 x 31 x 86 x 69 = 1013586540
Therefore, the lowest common multiple of 290,551,899,860,138 is 1013586540.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
290 x 551 x 899 x 860 x 138 = 17048525602800
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
290 : 1, 2, 5, 10, 29, 58, 145, 290
551 : 1, 19, 29, 551
899 : 1, 29, 31, 899
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,551,899,860,138, is 1.
Now, the common factors can be found like this.
290:2x 5x 29
551:19x 29
899:29x 31
860:2x 2x 5x 43
138:2x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 29x 29 = 16820
Therefore, the value for common factors is 16820.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 17048525602800/(1x16820)
LCM = 17048525602800/16820
LCM = 1013586540
Thus, we can understand that the LCM of 290,551,899,860,138 is 1013586540.
